You are considering replacing a traditional MPLS WAN with a SD-WAN solution. Which two statements are true in this scenario? (Choose two.)

Question

Options

• ASD-WAN requires the use of specialized ASICs to route application traffic.
• BSD-WAN can provide similar security and privacy to legacy WANs.
• CDirect Internet Access can be made available in remote offices using a local breakout.
• DDirect Internet Access can be made available in remote offices using a central breakout.

• A
  21% (5)
• B
  71% (17)
• D
  8% (2)

Explanation

B is correct because SD-WAN can replicate the security and privacy of MPLS by encrypting traffic over public internet links using IPsec tunnels, plus layering on next-gen firewall capabilities - making it functionally comparable to the inherent privacy of MPLS's label-switched paths.

C is correct because a core SD-WAN advantage is local internet breakout - remote branches send internet-bound traffic directly out to the internet locally, rather than backhauling everything through headquarters. This reduces latency and conserves WAN bandwidth.

A is wrong because SD-WAN is defined by running on commodity (x86) hardware using software policies - no specialized ASICs required. That's largely the point: it's cheaper and more flexible than proprietary hardware-dependent solutions.

D is wrong because central breakout is the old MPLS model (hairpinning traffic back to HQ before it reaches the internet), which SD-WAN is designed to replace. Local breakout (Choice C) is the correct SD-WAN term.

Memory tip: SD-WAN = Software (no ASICs), Direct access via Local breakout. If you see "central breakout," think "that's the legacy way" - SD-WAN breaks out locally.
